TESSEK Ltd. was founded twenty years ago as a joint-venture of two biotechnology firms: one was SENETEK, a western company engaged in biochemical industry, the other was TESLA VHJ, a state owned company active in polymer separation research and production of laboratory instruments. TESSEK Ltd. went through a complicated privatization process during the early nineties. The company got rid of unprofitable business activities and as a small healthy private owned company resumed its main production program - sorbents and columns for High Performance Liquid Chromatography (HPLC) based on patents developed mainly by the Institute of Macromolecular Chemistry, Academy of Science of Czech Republic.
TESSEK Ltd. produces sorbents based on an inorganic matrix (silicagel, SEPARON SGX) and an organic copolymer (copolymer of 2-hydroxyethyl methacrylate and ethylene glycol dimethacrylate, SEPARON HEMA) respectively. The production program of TESSEK Ltd. includes sorbents and columns for both analytical LC and large scale preparations.
These high quality products are commonly used in hospitals and other health service centres, biochemical laboratories, research and testing laboratories active in the field of medicine, hygiene, pharmacy, drugs, food production and quality control, air and water pollution monitoring, agriculture, veterinary medicine, fermentation (e.g. wine production and beer brewing industry), university laboratories (analytical chemistry, biochemistry etc.).
